Rapunzel's Castle

I could hear the tour guide explaining this and that to his followers who seemed genuinely interested in looking at everything he was pointing at — on the outside of the castle. Nobody of them had the slightest idea that right behind the wall they were looking at, a radically different type of tourism was under way. Literally a parallel world that they couldn't enter, just because of their own narrow-mindedness. Standing on the right side of the wall was kind of an exhilarating experience.
